But in trading and as a trader it's helps you be a bit rational and less irrational in decision making, rather than being emotional when you have losses in trading, you should actually see it as something that's always meant to happen. Its like a learning process that never ends.
Anytime you trade always be self prepared for losses, but at the same time keep your hopes high for positive results.
It’s true we should keep our expectations high because that is what will make us focus and trade with no fear. As a trader, losing is something that must happen whether a trader likes it or not. Losing is part of the journey, but many traders did think it was a normal thing that happened to traders; they thought they would get profit all the time, which is not true. Every investment has a risk attached to it, and the risk that is behind trading is money that you will easily lose, especially if you have deep knowledge of trading. You are at high risk of losing money.
Emotions are always another factor why some traders lose money, especially if they lose in their previous trade. They put it in my mind that they must recover the loss from the next trader. The last thing I will mention that you forget is greed. Many traders are greedy; they are not ready to learn, and they put too much hope on trading.
